Two-Dimensional Gas of Disks: Thermal Conductivity

Journal of Statistical Physics, volume 82, pages 1453-1466, (1996)

Index

The phenomenon of heat conduction in a two-dimensional gas of N hard disks is studied in
the hydrostatic regime by means of nonequilibrium molecular dynamics (N ranging from
100 to 8000). For systems with N >= 1500 the temperature and density
profiles observed are in excellent agreement with the continuous theory, but the conductivity k
differs from the one derived from Enskog's theory in a systematic way. This difference seems to slowly
decrease with increasing density.
